Abstract

UNA SEÑAL DE IMAGEN DE ENTRADA ESTA DIVIDIDA EN BLOQUES. LOS BLOQUES ESTAN AGRUPADOS EN GRUPOS, CADA UNO DE LOS CUALES TIENE UNA PLURALIDAD DE BLOQUES. LA SEÑAL DE IMAGEN DE ENTRADA ESTA CODIFICADA DENTRO DE UNA SEGUNDA SEÑAL DE IMAGEN BLOQUE POR BLOQUE. LA SEGUNDA SEÑAL DE IMAGEN UTILIZA UN CODIGO DE LONGITUD VARIABLE. UNA SEÑAL DE CORRECCION DE ERRORES SE AÑADE A LA SEGUNDA SEÑAL DE IMAGEN PARA CADA UNO DE LOS GRUPOS. UNA SEÑAL DE LA DIRECCION DE COMIENZO Y DE LA DIRECCION DE LOCALIZACION, SE AÑADEN A LA SEGUNDA SEÑAL DE LA IMAGEN PARA CADA UNO DE LOS GRUPOS. LA DIRECCION DE COMIENZO REPRESENTA UNA POSICION DE UN BIT DENTRO DE CADA GRUPO. LA DIRECCION DE LOCALIZACION REPRESENTA UNA POSICION ESPACIAL DE UN BLOQUE DENTRO DE CADA GRUPO.
